Subject: [PATCH] cloud-init: Set default datasource list

When no DataSources list is specified then the automatically used default
list of (all) Data Sources includes "CloudSigma" and "SmartOS" which
require the py3-pyserial package to be installed (which is *not* listed
as a dependancy of the Alpine cloud-init package) and, if/when not
installed, then during boot cloud-init gives multiple errors when
checking those DataSources.

Add a replacement "default" list of DataSources to /etc/cloud.cfg that
includes all except CloudSigma and SmartOS, so avoiding errors when
someone has not tailored the DataSources list.
